Introduction: urner's syndrome (TS) is a rare genetic disorder related to the total or partial absence of an X chromosome, affecting 1/2 500 newborns of female sex. It associates almost steadily a delay in stature and ovarian failure with infertility.The other anomalies are inconstant: morphological features of variable intensity, associated malformations and an increased risk of subsequent acquired diseases.The diagnosis of certainty is established after ...

Introduction: Pituitary stem interruption syndrome (PSIS) is a congenital abnormality of the pituitary gland responsible for pituitary insufficiency. Its prevalence is unknown but about 1000 cases have been reported to date. It is characterized by a triad associating a very fine or interrupted pituitary stalk, an ectopic posthypophysis (PH) or absent and a hypoplasia of the anterior pituitary, visible on the MRI. The etiology of PSIS remains unknown.<p cla...

Objectives: Familial hypocalcemia is a rare autosomal dominant disease characterized by hypercalciuric hypocalcemia. The disorder is caused by heterozygous mutation in the CASR gene that encode a calcium-sensing receptor in parathyroid glands and kidney tubules.Clinical case: The boy was born at term from non-consanguineous parents with normal length and weight. On the second day of life he was admitted to an intensive care department with convu...

Keywords: Primary adrenal insufficiency, X-linked adrenoleukodystrophy, early manifestationBackground: The primary adrenal insufficiency (PAI) in patients with X-linked adrenoleukodystrophy (X-ALD) is known to develop commonly after three years of life and there are little cases with an early manifestation described. Here we report cases of early PAI manifestation in X-ALD patients.Clinical...

Objectives: To investigate changes in levels of autoantibodies(Abs) against 21-hydroxylase(21OH) in APECED patients and in patients with isolated primary autoimmune adrenal insufficiency (AI) over time after manifestation of AI.Methods: 24 patients with APECED with AI and 5 patients with isolated autoimmune AI were recruited. APECED was confirmed by finding at least two major components of the disease and/or two mutation...

Objectives: To investigate sensitivity, specificity and predictive values (PPV, NPP) of autoantibodies against 21-hydroxylase in APECED patients with and without adrenal insufficiency (AI) and in patients with other forms of AI.Methods: 42 patients with APECED and 24 patients with other forms of AI were recruited. APECED was confirmed by finding at least two major components of the disease and/or two mutations in AIRE gene and/or high levels of antibodie...

Background: 46,XX DSD (Disorder of Sex Development) includes individuals with ovotestes (ovotesticular DSD (OTDSD)) or testes (testicular DSD (TDSD)). Most individuals with 46,XX TDSD carry the SRY gene. Other known causes of TDSD/OTDSD include chromosomal rearrangements involving SOX9 or SOX3 and mutations of WNT4 and a WNT regulator, R-SPONDIN 1. However, our understanding of the molecular causes of TDSD and OTDSD remain incomplete.<p ...

Background: Diabetes mellitus (DM) is one of ‘minor’ components of autoimmune polyglandular syndrome type 1 (APS1). The prevalence of DM in APS1 varies from 2.5 to 18% in different populations.Objective and hypotheses: To study disease phenotype and genotype of APS1 patients with DM.Method: All patients diagnosed with DM were selected from the Russian registry of APS1 patients. Clinical data, AIRE-gene mutations and immun...

Background: The ganglioneuroma (GN) is a benign tumor of the sympathetic nervous system following the sympathogonies that affects children and young adults. This is a rare tumor (7/1 000 000) which can be located along the sympathetic chain from the neck to the pelvis. In 20% of cases, the GN is localized in the adrenal.Objective and hypotheses: Report observations of eight patients with GN.Observations: Eight patients (two boys an...

Background: Achondroplasia is the most common cause of genetic dwarfism with a prevalence of 1/10 000 to 30 000 birth. It is a pathology of dominant inheritance linked to the mutation of the receptor gene growth factor on chromosome 4p16 fibroblastes FGFR3 responsable rhizomelic dwarfism and multiple complications likely to compromise the functional and vital prognosis of patients.Objective and hypotheses: Find the frequency of neurological complications...
